Subject:  FIX: Using LTModem Linux Driver with Xircom PCMCIA Network Card
   Date:  29 Jan 2002 02:34:53 -0600
   From:  Jeffrey Phillips <jeffrey.phillips@staffeon.com>

The LTModem hardware detection process may cause an inserted Xircom
PCMCIA network card to malfunction and the lt_modem and lt_serial
modules to improperly load.  Although the lt_modem and lt_serial
modules appear to be successfully loaded and the modem appears to
initialize; the modem will always report "NO DIALTONE" when trying
to dial and connect.

Starting with official ltmodem release of 6.00b14, there is a new
optional "No Detection" value added to the lt_modem module's "Forced"
parameter.  If the "No Detection" value is set to 1, then the module
will by-pass all hardware detection for the LTModem.  Either a blank
(because it is optional) or a 0 value will cause the driver to probe
for the resources even though the IRQ and I/O address have already 
been set with the Forced parameter.

To use the new "No Detection" value run:
# modprobe lt_modem Forced=3,0x130,0x2f8,1

Or edit the /etc/modules.conf and add the following:
options lt_modem Forced=3,0x130,0x2f8,1

For full discussion of the first three values in the Forced parameter,
see the Insert-param.html file in the LTModem Documentation which is
distributed with the driver, or the inside DOCs.tgz file found on the
main Ltmodem Linux Driver website: http://www.heby.de/ltmodem

An easy way to test if you need to set the "No Detection" is:
1. Run 'lsmod' and see if the lt_modem and lt_serial modules are loaded.
2. If they are loaded, unload them by running `rmmod lt_serial lt_modem'.
3. Insert and make sure your Xircom PCMCIA network card is working.
4. Try to dial out using your modem.
5. If you get "NO DIALTONE" returned, and your Xircom card might not
   have a network connection anymore then continue.
6. Eject the Xircom card.
7. Unload the ltmodem drivers by running `rmmod lt_serial lt_modem'.
8. Now try to dial using your modem.
9. If you successfully get a dial-tone, and connect then you probably
   need the "No Detection" parameter.  If you still get "NO DIALTONE"
   then you probably have another problem and should look at the Docs,
   or ask for help in the discussion area.

The above test is based on a Xircom CBEII-10/100 Cardbus, that does
_not_ have the LTModem integrated into the PCMCIA card.  If you have
a Xircom network card with a built-in LTModem and are getting the
"NO DIALTONE" you may need to just try out the "No Detection" and
see if it fixes your problem.

Thanks Mark Spieth for adding the "No Detection" parameter.
